Abstract

L'invention concerne un dispositif visiocasque (100), comprenant un premier système optique (10) et un second système optique (20). Le premier système optique comprend N premiers écrans d'affichage (11), et le second système optique comprend N seconds écrans d'affichage (21). La lumière émise par les N premiers écrans d'affichage est focalisée sur un deuxième élément optique (13) à l'aide de N premiers éléments optiques (12). La lumière focalisée sur le deuxième élément optique est focalisée sur l'œil gauche à l'aide du deuxième élément optique. La lumière émise par les N seconds écrans d'affichage est focalisée sur un quatrième élément optique (23) à l'aide de N troisièmes éléments optiques (22). La lumière focalisée sur le quatrième élément optique est focalisée sur l'œil droit à l'aide du quatrième élément optique. Étant donné que N est supérieur à 2 et que la lumière émise par les N premiers écrans d'affichage et par les N seconds écrans d'affichage peut être focalisée sur des yeux humains à l'aide des éléments optiques, la résolution et l'angle de visualisation du dispositif visiocasque sont améliorés.
